G-green B-blue indigo V violet 3rd character is H or T (Heads or Tails from flip of coin) 4th character is 1-6 (roll of die) Write down any 5 valid codes If S is the sample space, calculate IS| For the event, where the first characters is "A", and the color is green, list the elementary events of the event, and give the size of the event set Assume that all outcomes of experiment are equally likely. Find the probability of the event in step c a) b) c) d)
